Does supplemental feeding of red squirrels change population density, movements, or both? Does supplemental feeding of red squirrels change population density, movements, or both?
Supplemental feeding increased the number of red squirrels (Tamiasciurus hudsonicus) captured on two trapping grids, leading Sullivan (Journal of Mammalogy, 71:579–590, 1990) to infer that the population density of residents had increased. This conclusion is questionable because the residency status of captured squirrels was unknown.

Application of a computer simulation model to migrating white-fronted geese in the Klamath Basin Application of a computer simulation model to migrating white-fronted geese in the Klamath Basin
The Pacific greater white-fronted goose (Anser albifrons) population has declined precipitously over the past 20 years. Loss of wetland habitat in California wintering areas has had a significant effect on the population, so recovery of the population may depend on innovative management of the few remaining wetlands. A computer simulation model, REFMOD, was applied to greater white...

Diurnal flight time of wintering Canada geese: consideration of refuges and flight energetics Diurnal flight time of wintering Canada geese: consideration of refuges and flight energetics
We monitored individual radio-equipped Canada geese (Branta canadensis) associated with a federal refuge to assess flight activities from late fall through spring. The number of flights per day was lowest in late fall when most geese remained within the refuge and highest in spring when they moved increasingly beyond the refuge area. The only significant seasonal difference in flight...

Brood parasitism among waterfowl nesting on islands and peninsulas in North Dakota Brood parasitism among waterfowl nesting on islands and peninsulas in North Dakota
During 1985 and 1986 I studied interspecific brood parasitism among seven species of waterfowl nesting on 36 islands and 24 peninsulas in central North Dakota. On islands, 40% of 178 nests were parasitized with an average of 4.3 parasitic eggs, and on peninsulas 2% of 275 nests were parasitized with an average of 2.2 parasitic eggs. Redheads (Aythya americana) were the primary parasite...

Impacts of changing irrigation practices on waterfowl habitat use in the southern San Joaquin Valley, California Impacts of changing irrigation practices on waterfowl habitat use in the southern San Joaquin Valley, California
We used diurnal aerial census data to examine habitat use patterns of ducks wintering in the southern San Joaquin Valley, California from 1980-87. We calculated densities (birds/ha) for the northern pintail (Anas acuta), mallard (A. platyrhynchos), green-winged teal (A. crecca), cinnamon teal (A. cyanoptera), shoveler (A. clypeata), ruddy duck (Oxyura jamaicensis), and total ducks in...
